“…According to this technology, the data in the R/W are saved as "temporary data" in the center server even when the R/W cannot catch the "data-process completed" signal. If the next processes are completed normally, the consistency of normal data sent to the center server and the previously-saved data is checked and the "temporary data" is revised as "definite data" [12].

Advancement in computer and communication technologies have resulted in an explosive growth in embedded systems. The market and users requirements have been rapidly changing and diversified. Under these evolving situations, the assurance to keep the continuous system operation of embedded systems is becoming more and more important. The Autonomous Decentralized System (ADS) has been proposed for resolving the on-line property to achieve the step-by-step expansion, maintenance and fault-propagation prevention for high assurance. This architecture is effective to improve the reliability and reduce the development cost and product cycle time to market by data-driven mechanism. The technologies have been applied in the IC card system for train fare collection and its effectiveness has been proven.

“…Processing time at terminals in DF1 is required to be under 0.2 second. In this short time, they need to detect, authenticate, read, judge, write, and verify IC cards [40] in addition to fare calculation, which takes the most of the time of all processes.…”

“…It is very convenient for passengers, but it is prone to instability in communication due to improper card use. This section introduces the autonomous decentralized data consistency technology (ADDCT), which recovers missing data caused by such unstable communication [40]. This technology has two derivatives: Single-layered data consistency technology [42] and Multi-layered data consistency technology [43], [44].…”

“…The time of staying within the communication area depends on the holder's behavior. According to the statistics, the minimum required time is 0.2 second [40], [54], [55], the time period which the autonomous cooperative processing technology targets. However, some passengers do not handle the cards properly, and the card thus cannot be processed.…”

The advancement of technology is ensured by step-bystep innovation and its implementation into society. Autonomous Decentralized Systems (ADSs) have been growing since first proposed in 1977. Since then, the ADS technologies and their implementations have interacted with the evolving markets, sciences, and technologies. The ADS concept is proposed on biological analogy, and its technologies have been advanced according to changing and expanding requirements. These technologies are now categorized into six generations on the basis of requirements and system structures, but the ADS concept and its system architecture have not changed. The requirements for the system can be divided in operation-oriented, mass service-oriented, and personal service-oriented categories. Moreover, these technologies have been realized in homogeneous system structure and, as the next step, in heterogeneous system structure. These technologies have been widely applied in manufacturing, telecommunications, information provision/utilization, data centers, transportation, and so on. They have been operating successfully throughout the world. In particular, ADS technologies have been applied in Suica, the IC card ticket system (ICCTS) for fare collection and e-commerce. This system is not only expanding in size and functionality but also its components are being modified almost every day without stopping its operation. This system and its technologies are shown here. Finally, the future direction of ADS is discussed, and one of its technologies is presented.
